Hi all, im a new member and a high shcool Algerbra student. Im having quite a bit of trouble with this homework(which is being graded as a quiz ) To start, i dont under stand what some of the questions are asking me, for example the first one is(this is in the intergrated algerbra AMSCO text book pgs 294-295 if any of you happent to have it ) the first question is if line AB and line CD intersect at E, Angle AEC=2=x+10 and angle DEB=2x-30, find angle AEC I have no idea how to even set this up, my own notes dont even explain it. I would be very apreceative if anyone could help
OH! *facepalm* I was using a diagram the text book page had given me that looks similart to what i thought it would look like....Sorry, but i think i got it figured out.
I think its x+10+2x-30=360
But the check for it comes out to be 359.8, but then again i suck at math....so this is wrong correct?
anyway, note that my equation has four angles in it. yours has two.
Final Hint: see number 10 here
that will give you the right equation to solve for x. note that "x" is NOT what you are looking for. you use it to find your answer.
